Change Managament multi-platform support, setup support, consulting

Hey all,

I know this topic has been beat to death  (by me even), but it looks like
we finally might be ready to evaluate change management systems, and i had
a couple of questions that aren't answered in the archives.  - I'm not
looking to rehash what's already in the archives, just looking for the
answers to the questions at the bottom of this post.

First a little background:   It must be gui.   It must be multi-platform,
with strong iseries implementation.

We will be using it for the following application environments:   iSeries:
traditional rpg, cobol, etc, some IFS related stuff - HTML, javascript,
net.data, eventually WDSC.  WinNT: Peoplesoft,  Cognos, Oracle, MS Access.
Crystal Reports.

Our plan is to evaluate the top 3 iseries CMS vendors (aldon, softlanding,
MKS) but will consider others if they meet requirements.

Now, my questions:  In your experience;

1.  Who has the best multi-platform support?  - i.e.  we don't want a
package where support for one platform is good, but other(s) are an add-on
or after thought.

2.  We'd like the vendor (or a qualified consultant) to come on-site, for
setup and training - ideally for as long as it takes to install the
product, interview users, devise/design a strategy, and configure, set up,
test and train users on the system.   Do any of the major players provide
this service?

Responses from vendors welcome.

Thanks!

Rick.
