Sure.  We could re-probe the converters when something fails and then
use the other converter, for instance?  Or we could just probe every
time, but keep a table of what we've tried.

Or we could probe all the converters at startup, and maintain a mapping
of which converter does what -- that sounds cleanest.

Sure.  Patches for a) and b) are welcome.  :-)

I dunno...  there's security implications.
