Hi John,

yes it is possible, but there are some drawbacks. There is at least the
different setting of  

var  $pi_checkCHash = TRUE;

for USER and USER_INT, that you could in fact switch with an
additional TS parameter, not by the user, but somehow in the extension
automatically.

But I regard the $pi_checkCHash concept as a completely unnecessary
setting and hope it will be obsoletet soon. Which would make USER/USER_INT
switchin more simple:

See: 

http://t3flyers.wordpress.com/2007/04/04/rfc-caching-useruser_int-switching/

Read the following thread (second part):

http://lists.netfielders.de/pipermail/typo3-team-extension-coordination/2007-April/001757.html


Second you need to switch the cHash on/off in links pointing to a plugin
if you really would like to switch a special view. But you will rarely do
this in practice. Usually it is unambigous if a special part of a plugin
will be used as USER or USER_INT (form vs. details).

With this in mind it should be possible to use one plugin with a double
nature of USER/USER_INT. That is indeed a good suggestion for improvement
of existing plugins and worth some research.

But it is more difficult to explain to a beginner building a new
extension, than to tell him simply to use two different plugins.

A specialized form of this concept is the USER/USER_INT pair within a USER. 

Example:
http://typo3.org/extensions/repository/view/efaq/0.1.5/info/configurations%252Fsetup.txt/

The original concept http://www.4any1.de/www.4any1.de?id=2346

Elmar
