What OS? Do you mean double buffered (for continuous ongoing sampling) 
or is single-shot OK?

Generally, there's probaby a C library to do what you want, so there's 
the option to wrap it.

For Measurement Computing devices, see 
http://www.its.caltech.edu/~astraw/pyul.html . There's a 'Also of 
interest' section on that page. I've also got a Pyrex wrapper for Jasper 
Warren's linux PMD1208FS code which I may be able to put online if 
there's interest... Note that none of this stuff is extensively tested, 
but it's a start, anyway.

Comedi comes with a Python interface, but I haven't tried it.
