T7 RNAP can be used in eukaryotic systems and Vacinea T7 vectors for the
expression of proteins do exist and have been published.  I don't have the
reference/s on hand but I believe the paper is by W. Alexander with B.
Moss and T. Fuerst.  I'm not sure if a more recent paper has made it to
press but a refinement of the system with a temperature sensistive lac
repressor has been accomplished.  These vectors were made at MedImmune
Inc. but might be obtained from the Bernie Moss lab and NIAID NIH.
