Of course I can - in your Zaurus :-) You must have a zaurus to legally use opera on your simpad :
1) buy a zaurus
2) update the rom to install the new versions of the commercial apps (like opera6)
3) remove opera6 from the zaurus and install the .ipk on the simpad - that's it ! It's just the standard procedure used to put back opera6 when you have flashed your zaurus to OPIE.
In theory you could do the same with hancom office suite but the latest version of their applications depends on some libs. I didn't take the time to find a way to fix that - if you can, do not hesitate to tell me.
In any case, you should not make illegal copies of opera6- opera is a great company offering excellents products for many platforms. Opera6 on the zaurus is IMHO the best browser currently available - netfront being a close 2nd and konqueror requiring much improvements.
Making illegal copies would mean new versions could not be legally used on a different hardware due to some restrictions which would be added.
