From the protocol & core implementation POV there's absolutely no
problem at all - the protocol is language agnostic & all the different
language bindings use the same low level C APIs under the hood. If
you do have issues, they'll either be bugs in the bindings (which
should obviously be reported in the bug tracker), or a result of
the binding / application not implementing the full set of capabilities.
In the latter point, I'm thinking particularly of introspection data
support - if its incomplete there can be subtle data type conversion
edge cases between strongly & weakly typed languages. That said, the
introspection support is pretty good these days, so writing clients
with a different binding to the server is likely to be troublefree.
Even several releases back before introspection was completed, I
could quite successfully mix & match Perl+Python on both ends.
