Here is a kind of solution which does not involve a jailbreak. I use Teamviewer on my iPad to see and control the screen of my Windows PC back home. Of course my windows pc has IE and ActiveX so I can see the web cam or surveillance cam on my iPad by using Teamviewer to look at my PC monitor back home.
By the way, if you are traveling in China and want to get past the censored sites (e.g BBC, Google, Poker, Porn, Gambling) etc you can use Teamviewer in the same way. I use it on my iPad to play PartyPoker while in China, again via my home PC.
