For anyone that wants to do this yourself, here are the steps I used.
1. I created a page on Google Sites. This is where I uploaded the executable swf file and sgf files.
2. Download Gludion. The only file you need is the file goswf.swf.
3. Use the menu in the upper right of Google sites to "manage the site" and on the left had sidebar there is an option to upload attachments. Upload the goswf.swf file and an sgf file.
4. In blogger, or presumably anything similar, you can embed the player using html like this:
<embed src="http://sites.google.com/site/kidschessandgo/goswf.swf"
flashVars="c0=#83E9F3&c1=#E5E5E5&c2=#AABBAA&url=wanhychen-Hisashi.sgf" quality="high" allowscriptaccess="always"
type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer"
align="middle" height="400"
width="400"></embed>
And Presto!
