I wonder when using the word *irco*oft will automatically discount
anything as a *real* solution, the way *BM does now (but they are
getting better.) [Sorry, the devil made me do it.]

Thanks for the URL. I read the draft and it is the old 70's
2P Commit Protocol. Many databases only implement up to
isolation level 2 and sometimes 3. In those cases old 2PC
works fine. To go to isolation level 4 in a distributed database
you need *more*.
I will implement TIP on the TCP side of the platform (in the CPU
servers) but I need something stronger on the IL side with the
file servers.
Thanks for the info.
