Calling installed SysApps from the [untrusted] web?

Pardon for being a n00b but the following is fundamental
for the WebCrypto.Next project...

Can you call installed (signed and packaged) web-apps from
a ordinary hosted web application?  How would they interact?
Could you "IFRAME" and postMessage() a sysapp?

Cheers,
Anders
