First of all, Perma-Haste, much like a few other overly powerful feats, abilities, etc (Dev Crit, HiPS, etc) are unbalanced.
I really think enough has been said about it in this thread, so I will just offer that I am personally against Perma-Haste, because it is an "all or nothing" sort of thing in the game - either all have access to it, or no-one should. It is just that unbalancing.
I prefer to just keep Haste (even extended, yadda yadda yadda) and such in the game instead.
Perma Haste turns a Spellcaster into a Super Spellcaster, and they basically don't need the extra power anyway...
I have a bone to pick with SHOVA here - the teleport spell is rather limited??!! I beg to differ! It is majorly awesome! Not only is it a "get out of danger fast!" sort of thing (put it in a quickslot, bam! Gone!), but combined with Scrying...and you can really get around!!!!! Also, being able to port an entire party is sweeeeeet!!! Especially when you have LOTS of Summons!
I like to use it to port into a Magnificent Mansion...hehe....instant rest!!! Or in an Inn, if that is blocked (which it should be, IMHO). So Teleport can be used as the ultimate retreat and repower spell, and return you to the "scene" powered up and ready to rock! How is this then "rather limited"?
Combine it with a Contingency spell, and you are basically safe from being PKed...
So, IMO, there should be a special version of Haste designed just for me and my toons, all classes.
Actually, there is! It is called Expedious Retreat, and works just like you have described. One can have this 1st level spell easily put on items, and repeatedly cast. I have even seen ingenious uses of this in PWs, put on roads so that one can move faster on them...
There are also other ways to increase the speed of units, without giving the bonuses of Haste through scripting.
