Having upgraded to Joikuspot 1.1 I can happily confirm these obeservations during a quick test without WEP enabled:

-While activated the program no longer pushes 100% cpu time

-My Macbook Pro now recieves an IP address from Joikuspot DHCP server and can serve the internet. (Joikuspot 1.0 and our 2 Macbooks Snow Leopard didn't seem to get along and got stuck on self assigned ip address while windows clients worked correctly)

the program is more than worth the 7 Euro's I have paid for it.
