o.k firstly to answer your question.
-sceamernet is the software that runs the cue, it is built into lightwave... still is I think (don't use it much anymore)
secondly,
amiga's where NOT popular in renderfarms ever. Right around the time Babylon was being done lightwave was ported to PC just becasue amiga renderfarms where to expensive and slow.
Also Babylon 5 was NOT rendered on amigas for the first two seasons, it was only the pilot that used them.......you see the amiga was loosing ground even back then! Amiga where expencive NOT cheap!
lastly, for fun it may be cool to set up an amiga render fram, for productivity it would be retarded.
Also nothing form elbox is need or recomended, all you need an ethernet card like and x-surf which will cost you $120 IF you can find one (let alone 20x)
Still as a 3d guy, I would love to see/hear about your amiga render farm... I may even connect my 4000t and 4000d just for kicks but I need a second ethernet card.. and I tend to jam my systems full of zoro cards so I don't even know if I have enough space. LOL.
