This alone makes MP a winner against IIS.
I have had MP2 up and running for ~1 year (with some hand holding)
on live systems under win32. The number of IIS related attacks
on the boxes running AP2/MP2 is just scary.

Apart from some of the nasties that appeared on the list a day after
my client (or I) spotted them, all has gone well :-)

My problems with MP2 under win32 are;
1) the install procedure
    Projects such as openSA help enourmously because you can give
    an "MS head" a single .msi file and *know* they can install
    Apache+MP+perl+... via an understood interface.

2) Any dependencies upon ASperl.
    Activestate (perl support) is fast becoming a joke. Perl support
    appears to sporadic or non existant and 5.8.4 is simply not stable
    (ithreads under Win32 - io handle leaks etc)
    The only way I can safely use MP2 under win32 is to roll my own
    which causes its own problems.

3) interactions with win AV/firewall products (an AP2 problem)
    I have noticed that AP2/MP2 has problems when ran on systems
    that have some firewalls/AV software. Panda is one of the culprits.
    The explanation is that PAV does not provide a "full API" and
    this causes problems with apache but I have seen non technical
    clients blame AP2 as PAV is a commercial product so AP2 must be
    to blame. :-(

    Finding any of the above (apart from 1) can be time consuming
    for non developers who want to try out MP2. Adding stuff like
    this to a win32 FAQ would help a lot (IMHO).

On linux MP2 is shipped with FC3/MDK10 etc. IFAICS MP2 is the
de-facto standard :-)

Been using it for some time and no problems under linux at all :-)

Know of at least two sites (names under Non disclosure) who we have
moved to AP2/MP2 as part of a live system performance upgrade :-)

It may be worth HEADing some of the high end MP users to see
who has upgraded and include this info in the publication.

Do we know anyone at netcraft who can give us figures for AP2/MP2
commercial uptake?
