Database connectivity

[SectorUnknown]

I've written a database (Access mdb) front-end using Python/wxpython/and 
ADO. However, the scope of the project has changed and I need to access 
the same data on an MSSQL server. Also, the front-end needs to be cross-
platform (Windows and Linux). 

Does anyone have any suggestions on what database connectivity I should 
use? I've looked at mxODBC and wxODBC briefly, but am not sure what is 
the best way to go.

BTW, although I would love to move away from the MSSQL server, that's 
not going to change.
