I've considered the same thing myself. However there are a couple
of problems that even non-taxonmist, seat of the pants growers like
myself can see right off the bat:

1) slime - this stuf grows in the water in the trays and can
suffocate the utrics. The only answer would be to build a surge
tray type of setup with a recirculating water pump.

2) water depth. Usually trays only get 1" or water or less, which
doesn't seem like enough.

What about taking a plastic strawberry basket and filling it with
terrestrial utrics? Might this be good enough? I'm not sure if
there are any non-tropical terrestrials with big enough traps however.

Regarding trap size, Lees lists (I think) U. purpurea as an
aquatic with big traps, for sale. Based on what I saw in "DeathTrap",
even small bladders can trap and kill a larger larva, even if they
can't digest the whole thing.

Maries CP and Orchids sells some rare Nepenthes, but they aren't
cheap. Chuck Powell has also mentioned that he may be getting
some tissue cultured rare Nepenthes for sale this year. Orgels
and Lees are the best bets still I guess. Or try Gordon.
