I'm using a portable Python. (Sorry, should have mentioned that.)
So setting the script path is probably needed.
Using:

# Imports
import os
import sys
import vapoursynth as vs
core = vs.get_core()

scriptPath = 'h:/Output'
sys.path.append(os.path.abspath(scriptPath))

#import script A (h:/Output/scriptA.py)
import scriptA
original = vs.get_output()
#import script B (h:/Output/scriptB.py)
import scriptB
clip = vs.get_output()
# processing
if original.format.id != clip.format.id:
 original = core.resize.Bicubic(original, format=clip.format.id)
stacked = core.std.StackHorizontal([original,clip])
# Output
stacked.set_output()

I get:

Failed to evaluate the script:
Python exception: Plugin G:/Hybrid/vsfilters/SourceFilter/FFMS2/ffms2.dll already loaded (com.vapoursynth.ffms2)

Traceback (most recent call last):

    import scriptB

vapoursynth.Error: Plugin G:/Hybrid/vsfilters/SourceFilter/FFMS2/ffms2.dll already loaded (com.vapoursynth.ffms2)

Seems like the importing itself does work that way. Hurray!

Problem now is that both scripts use the same source filter (ffms2.dll) and thus the second script crashes on the LoadPlugin-line, since the Plugin is already loaded.

So:

• Is there a way to check whether a plugin is already loaded ? (won't help here since I don't want to edit the two scripts, but it might be helpful when I generate scripts)
• Might be a good idea if LoadPlugin would not cause a crash but instead simply ignore the second 'loading'-attempt.

Seems like currently import isn't the right way.
