Hello again!
If you want a 3D version, then this post:
http://www.gearthblog.com/blog/archives/2008/06/easy_embedding_of_the_google_earth.html
might be of interest, lists a number of services (the 3rd in
particular) that can embed KML.
(most should be able to take the KML produced by the 'View in Google
Earth' link on My Maps, or even better should be able to directly
consume the KML produced by GE Pro, and uploaded to a website
somewhere...)
