I totally agree with you Jenn. How long are they going to be there? Once and if you allow this, who knows what there network is like, I do not allow unknown networks access to my networks. I will not and cannot controll and monitor what is coming acrosss the line. Better safe than sorry. Never assume and trust no one, it can save you a lot of headaches. ; )

Oh well, it much depends on what kind of data / information your external
consultants work on. Does your policy have a classification criteria, if so
what does it say about, for the sake of example, the remote access of
confidential information? Do not forget, then, that once they unplug their
laptops they may have recorded YOUR data on their hard disks and can roam
happily on planes, trains and anywhere with YOUR data (and laptops are easy
to forget somewhere or to be stolen anyway).

I would be personally more concerned with administrative countermeasures
trying to technically assess their networks security (for example there may
be a clause in their contracts about (not) storing your data locally or
what kind of measures you ask them to take if they do).

Besides, if the tunnel is crypted (efficiently) end-to-end (or laptop to
border-router) what do you care what networks they traverse in the process?
