Not that I'm aware of. Depending on what it is you're looking to display you could use rss to grab elgg content and display it on another site. If it's content that is not public I have a plugin that allows for authenticated rss. It's not an elgg widget on the other site, but it could be styled like one.
@Matt thanks for your response
To elaborate on some of what Cash said:
Thanks guys!
THX to Brett and Cash ... you guys doing a good job .. and hope you will push elgg in a new sphere with 1.8 ... if you need some ideas ask me or check my featurerefquests in this forum ;-)
