    unsure, however, of what to look for in features of video editing
    equipment that will allow me to do this easily. 

I've worked with a few editing systems which have treated 3D field sequential 
footage just like regular footage, without destroying the 3D effect.  These 
include the SONY Hi-8 to Hi-8 desktop deck (EVO 9720?), the Amiga Video 
Toaster/Flyer combination and the FAST Video Machine.  I've also tested the 
Avid MCXpress and Media 100.  In spite of the different compression formulas
and variable compression rate algorithms, they all seem to handle 3D without
problems.

There is a unique situation which arrises, however, when your recording system 
lays down time-code that is not perfectly synchronized to the field
alternation. 
(This happens mostly in home-made systems that combine cameras which cannot 
share their reference signals with the recorder.)  Using tapes which have
already been 'pre-striped with time-code is also problematical.  When an
editing machine 'belives' the time-code over the field identification
'flags', you can get stuck with pseudoscopic images.  In some cases,
defeating the TBC on the playback deck will solve the problem.  I have
actually removed the TBC board from a SONY EVO-9850 Hi-8 deck in an editing
suite to resolve this issue.  

I can give you other solutions via eMail if you have any scenarios more
specific than that.
