Env Variables are one solution, a host specific config file another.
Such a file could be specified on the command line and/or looked up
by default in places like $USER/.toxhost.ini or /etc/toxhost.ini.
It could contain

    py25.basepython = /path/to/python2.5
    py26.basepython = ...
definitions.  They would override the definitions of the tox.ini file.
There could be a generic environment variable to a TOX_HOSTFILE=... setting 
to point to such a file as well. Would this work for you?

Don't think so.
