Well, just wanted to provide the results of my testing/experimenting. Since no one replied, I decided to simply try it. And surprisingly enough, things seem to be simply working exactly as I wanted. Alright, not exactly, but pretty close.
To revisit the situation, I have a large, hi speed desktop disk connected via an eSata card in my MBP 17. This drive stays in the office. Have been backing up to it for awhile using TM. Works fine. I also have a Costco Western Digital 250 gig drive portable USB drive that I travel with. I've now started doing TM backups to it, as well.
Two entirely separate backup scenarios. I simply go to System Preferences and simply "Change Disk..." and point to the desired disk. When I'm on the road, I've selected the WD portable drive. When I'm at home, I simply use the desktop drive. Gives me a level of security in the event of possible failure of either of the backup drives.
And unfortunately, the desktop drive does seem to be having issues - heating up excessively and then dropping off the desktop. So, I'm now creating a network backup to my dual G5 on a drive there.
The only issue I have, and I referenced it in the first paragraph, is that it seems the first backup when switching to a different disk sometimes takes a while. Nothing horrible, just a bit more time preparing. But nothing I can't live with it.
Your mileage may vary, but happy to answer any questions or provide any added info.
