can't you just run cpuminer with a .bat script or something like that on start-up, using one thread less that the amount of cores (just to keep the pc responsive)
As I said I am not able to install software on these pc's. About the only way is something browser based (client side).

for cpuminer you don't need to install software.
just copy the zip, decompress and run a .bat like:
Still to minimize network usage, you'd need to run the stratum proxy pointing properly to where are you mining
C:\guiminer\cpuminer\minerd -a sha256d -o
http://server:port -u user -p password -t number_of_threads
I foung something interesting: "Mining Javascript with WebGL", maybe it would help?
Thanks for the info.
