get_posts() for a specific site in multisite-installation

Hi,

At first let me appologize for posting this topic if this has been solved already. I used the search function but did not find anything useful or at least not what I wanted.

What I want is following, I want to display posts with the get_posts-function for a specific site from a multisite-installation, e.g. get_posts(“site=myblog”); As far as I know this only works for the “main”-site.

Is there a simple solution for achieving that?

Thanks,
best regards
Peter

PS: I know I could read/parse RSS feed for this site, but using get_posts is the preferred way
