Mauricio,
I've tested it and works fine, at least with tif files.
Few comments:
1. Add the ability to select the destination folder
2. Add a button to select/unselect display
3. Actually, better than the above, a similar plugin that would
just create the vrt file would be very useful. As the vrt file
might have many files (multispectral, hyperspectral, multi-temporal...),
this plugin could just read the list of files from a text file.
Thanks a lot for your contribution!

As a ubuntu user I also saw that problem. At the moment I'm using
GDAL's internals, not gdal_merge. You could say that the previous
version was based on gdal_merge as I read some of it's code to start the
plugin, but the recent upgrade is not really close to gdal_merge.
gdal_merge used the xml editing that I avoided in this version, so I
really implemented using python-gdal library. That's the only
requirement now.
Hope it works fine. I still don't know how windows and mac users are
going to cope with python-gdal, but I think I saw the package in the
osgeo repository.
All the best,
Maurício de Paulo

I also think that we should use gdal as much as possible,
the gdal_utilities are very good and I do use vrt files a lot
for time series of images.
But one problem is getting the appropriate gdal binary
for the different unix distros. For example, the current
gdal binary for ubuntu 8.04 (which is the LTS) is only 1.4.4 and does
not have gdal_merge, I had to download it separately.
How are you solving this problem? Are you including gdal_merge.py
or are you relying on the latest gdal version (which is 1.6.0 I think)?

Thanks for the interest, Augustin.
I've upgraded it to 1.0 API and made a huge change in code so that it
only uses gdal to set the VRT Raster, not xml messing anymore, so the
code should be more stable with gdal.
Again, the plugin is a gui to create a VRT raster colour composite. Gdal
does everything else by itself.
I should say that MANY features are being implemented in gdal through
VRT and other XML stuff (as wms). Maybe we should start thinking about
using VRT for other solutions (Filtering is the first easy one that I
think, but I truly think that gdal can war on the fly using vrt).
Thanks for testing,

Mauricio,
It would be great. Do you have it in a repository?
Can we try it?

I've written a RGB composition plugin using virtual raster and gdal.
Should I rewrite it to 1.0?
