I think most of the weight is in the battery. Big heavy battery means 
big heavy box. What battery are you going to use for 2 transmitters and 
a controller for 6-10 hours? If you use it for a homing beacon too 
that's an altogether different problem (100% duty cycle). And battery 
failure at a big important event with lots of people depending on you is 
bad news.

It's the same old problem - you can optimize for a few of the desired 
parameters, but to get them all is difficult. If you are taking wishes, 
here are mine:

1) lighweight.
2) dependable (and foolproof).
3) run for 2 days (2 transmitter sessions of 6-10 hours on 2 consecutive 
days) without recharging.
4) remote control, with each receiver on a different control frequency.
5) cheap.
