[plt-scheme] oracle driver for PLT?

Hi all,

I have a question inspired by YC's creation of the dbi interface.  
Seeing that there are currently drivers for mysql, postgresql and  
sqlite, I've started wondering how feasible it would be to write a  
driver for Oracle, and whether there would be any interest in the PLT  
community in having this?

Of course when I ask how difficult this would be, I know I'd have to  
multiply (exponentiate?) any estimations by an enormous factor, given  
that up till now I have never used FFI and have only rudimentary  
knowledge of C... and of Oracle too at the moment (but this could  
change).

So my question is more about the general feasibility (perhaps there  
are any obstacles I do not even imagine?) and whether you would think  
it desirable to have such a driver for PLT.

 From looking at how other languages communicate with Oracle, I guess  
one would have to use OCI, so in fact writing a scheme interface for  
the OCI functions (or the most basic ones, to start with).

I'd be very interested what you think about this?

Thanks,
Sigrid
