Is there a way that a Propeller could recognize the field strength of a Wifi hotspot [noparse][[/noparse]2.4Ghz] and output to a simple bar of 10 LEDs?

No not directly. Typically you would have a down converter that will bring the frequency down to a more manageable level. In theory this is easy, but in practice this is not an easy DIY task.
This is just an example, but if you took something like this...
http://www.eham.net/reviews/detail/5109
...A down converter for 2.4GHz that brings the frequency down to 144MHz, you could then generate a 56MHz to 37MHz signal from the Propeller to "AND" it through a mixer with the 144MHz to further down convert the signal so that it's within the FM broadcast band (88MHz to 107MHz)
If a 2.4GHz signal is indeed present, you should be able to detect it on a nearby FM radio ... If there is data present, you might even hear it.
Again, this is not an easy task for the do-it-yourselfer.

that will let you scan networks, and get the signal strength, you can then also try and connect to the network and if it is protected you can exclude that network from the results
Probably quite an overkill, but the answer is yes [noparse]:)[/noparse]
