Yesterday I started with it, you may find current helper in attached 
patch. It doesn't work yet,
the only thing I finished is to find a context and module name that 
redirects specified class,
that part works ok with some problems in existing context code:
---
/* query_index.ulAssemblyIndex = key_data.ulAssemblyRosterIndex; */
---
at this point returned index doesn't pass parameter validation in next 
QueryActCtxW() call,
but it's not a stopper for now and I forced it to 1 (2 was returned).

The main problem is that I still can't get module handle to this SxS 
library.
It's even worse, testing on Windows I'm not able to GetModuleHandle() 
for this library
with full path explicitly hardcoded. It's a bit strange.

After some testing on Windows I found that DllMain for mine library is 
called only after
attempt to CreateWindow() with redirectable classname and the following 
sequence produced:
---
DLL_PROCESS_ATTACH
call to RegisterClassNameW
DLL_PROCESS_DETACH /* disregarding that return value from registration 
call was success or not */
---
That's all done during CreateWindow() call.

I'd like to see some comments from kernel-knowledge developers - is it 
ok that SxS module load is delayed and
how properly replicate this outside kernel32 (inside user32 for this case).

Thanks.

True, this could be easily tested, but it's next part of the problem, 
first of load I need to
register classes.
