I have a suggestion to make Galaxy even more useful
You could enable direct data loading of Next-Gen sequence data from NCBI/SRA. As it is
now, if someone wants to make use of the NextGen tools, they have to upload a big data
file from their desktop. You have enabled very rapid data loading from UCSC, so perhaps
you can work the same magic to get data from SRA.
I normally just paste in the link to the gzipped fastq from SRA. This
works pretty well.
