I need suggestions on what kinds of systems are available to implement an
environmental control system for an aquarium that would be accessable via a
wireless 802.11 connection. Im just looking to control a light (on/off)
measure and control the water temp.

dallas semi has some serial controlled switches, 24bit address, you just  
send a data stream out to the device and it switches.  temperature  
measuring is simple as a probe and an adc, connect it to a digitally  
controlled pwm controller with an ultra slow clock and you have  
temperature control.
    you could do the same with an 8 pin PIC, a few hours of learnin, and  
building a simple programmer(noppp for instance).

not sure if this is what you're looking for but you might try the
Lantronix Wi-Port

It pretty much converts a serial connection to a TCP/IP connection
accessible via 802.11

Hope that helps.
