Why don't you use a SHtml.hidden with a callback?

I have a snippet (call it the "file manager" snippet) that creates a
list of snippet tags (each called "file deletion" snippets) to create
a virtual file listing with a deletion form next to each of the file
names.
These "file deletion" snippet methods need to somehow know their
corresponding file names so that the submit binding can delete the
correct file.
I accomplished it with something like the code at the bottom of this
message.
The general solution was to create the "file deletion" snippet tags
with a hidden input that contains the file name. The "file deletion"
snippet method, in turn, extracts the value out of the NodeSeq.
It works but seems inelegant. Is there a preferred method to do this?
Any feedback is welcome.
