Forwarding Google Voice numbers

Is this really the way it works with the Google Chat protocol? I ask because it is most assuredly not the way SIP connections work: With them, having two boxes trying to register to the same account simultaneously would leave both dueling for the connection, typically with an incoming call going to the last box to send a registration message.
Be careful making a generalized statement like that. It certainly isn't a requirement of the SIP protocol. As Steve mentioned, most VoIP providers require the use of sub-accounts for multiple registrations. But again, it isn't required by the SIP RFCs.
For instance, PhonePower allows up to 4 simultaneous registrations to the same line/account. All registered UAs ring at the same time. If memory serves me right I believe Vestalink is the same way as was Sipgate. I can assure you there is no "dueling for the connection." Any dueling for the connection you may have experienced was imposed by the VoIP provider, not by "the way SIP connections work."

Today I want to talk about one of my favorite aspects of SIP – multiple registration. With multiple registration, I can be in more than one place at the same time. Personally, I use it to be in three places at the same time. Using the same user ID and password, I register my Avaya 9641 desk phone, One-X Communicator for IOS iPhone client, and iPad Communicator. Every time someone calls me, all three devices ring.

Thanks for the clarification, Taoman. As the saying goes, we learn something new every day and sometimes it's that what we had learned previously was wrong.
If I recall correctly, I think Google Voice allows up to 5 forwarding end points. So, is it fair to say that one could have up to 5 OBi boxes connected to the same Google Voice account?
In any event, it would make it worthwhile to throw a spare OBi200 in your travel bag.

Why do you want to do this?
I don't want to give out the 0000 number to people. Instead, I want to give out the 0001 and 0002 numbers. However, I still want to be able to make outgoing calls from all three of those numbers using the OBi devices, but if someone calls 0001 or 0002, I want those calls to forward to 0000 where I can either answer the call, or let it go to Google's voicemail (the voicemail for the 0000 number). I want all of the voicemails in one account (0000's) instead of three separate ones. I was hoping to achieve this with Google Voice only and no other service.

No, that's not how it works. OBi devices emulate Google Chat clients. Google Voice treats Chat as one of its forwarding destinations. You can have up to six US PSTN (10-digit) telephone numbers on the list, in any combination of land line or mobile, plus Chat for your OBi(s).
It doesn't matter how many Chat clients are logged into your Google Voice account at one time; it counts as one forward as far as Google Voice is concerned. I suppose there's a theoretical limit to the simultaneous Chat sessions supported, but for everyday purposes, you're not going to hit the limit.

No, that won't work with Google Voice. You'll need to use a SIP VoIP service provider instead.
