I can vouch for other vendors, but I imagine this would work fine as
long as only one servlet at a time can be using the object reference.

Serialization is not known for being concise. I imagine it would be several
hundred bytes. It would be ok for a hidden field but you wouldn't want to
embed it in URLs (avoid URL rewriting if you have lots of URLs to the second
servlet on the same page).
