Nope, not out of the box.

If you look at the documentation, you'll find instructions on how to include the whole blog. Perhaps you can make simple modifications to suit your needs?

Thanks Lars, I'll try to have a look at it over the weekend.

Another question I have is whether it is possible to control the number of blog entries that show up on the blog home page.  It appears that they are all displayed which can obviously lead to long pages.  It would be cool to have a parameter which controls the maximum number displayed on the home page.

James,

They are not all displayed. Can't remember the exact amount (or time span) of entries shown, though. I guess both the blogger home page and includable snippet use same proc to get the entries, so it shouldn't be too hard to put there a parameter for maximum number of entries shown.

The default is to show 30 days worth of posts. I hacked mine to show a certain number of posts, based on a parameter. If the parameter is set to 0, then it's ignored and 30 days of posts are shown. It's currently PG-only cuz it uses the LIMIT clause, but here it is in case you want it as a base to start from:
