Option 1. Maybe this will work:
1. create a form where pressing a button causes a request to the remote
wiki, but don't expect the remote wiki to tell you the PTV value
2. in the local action associated with pressing the button, do
$t = file("$remoteWikiAddress?n=$pagename&action=source");
3. process the source held in $t to extract the required PTV
4. display the result of the PTV request using the same technique
used to display search results
Option 2.
Alternatively, if the remote wiki is willing to do some work,
one ought to be able to customise the action=dc Dublin Core
feed to include PTV name and value pairs, which the requesting
wiki can then unravel. In this approach, step 2 above becomes
$t = file("$remoteWikiAddress?n=$pagename&action=dc");
Option 3. (the easiest, if the host is willing)
If the requesting wiki is willing to do even more work, you
could create a regular external link of the form
"$remoteWikiAddress?n=$pagename&action=dc&ptv=vname"
Then you just click on the link to see the result. This would
be the easiest solution, but requires a willing remote host.
