Sure, when I've had time to rewrite the apps.

I'm not trying to be flip, I mean it since I'm interested in porting to Lazarus
and preferably getting off x86. Right now the apps use ODBC but I'm planning a
server upgrade since I need some of the newer facilities and want to eliminate
as many points of failure as possible.

What would be nice would be if ODBC could itself failover between servers, but
from the point of view of this ML that comment's just from another kvetching
luser- I've got neither the time nor the C expertise to get directly involved.
