I am thinking of gnu parallel. see this:
> echo /dir1/program1 /local/dir2/subdir/program2 ~/scripts/test
> /another/one/script4 | xargs -n1 echo | parallel --dr -n1 "cd {//};{/}"
> cd /dir1;program1

> cd /home/datakanja/scripts;test
> cd /another/one;script4
# explanation: 4 arguments get splitted into lines by xargs, then
parallel shows, what it would execute simultaneously (--dr = dry-run)
