Devicescape (Easy WLAN) sounds like a very useful utility. It allows me to easily connect to WiFi networks and it appears on my phone as a single access point - so I can configure apps (such as VoIP) to use the devicescap AP without regard for which network I am actually connected to.

On the other, it forces me to enter my network credentials on their web site. This is fine for public hotspots, and I guess this is OK for my home network, but this is definitely not OK for work. It also won't work anywhere that you don't have access to the Internet, or in environments that use 802.1x enterprise security.

Is there any other software that, like Devicescape, will allow me to aggregate all my WiFi networks into a single access point, but that lets me keep my passwords on the device (rather then their server)?
