ice for shields, and other grit-tech stuff

[Puke]

some well-read sci-fi fan posted on another thread, the concept of blowing water into space so that it will vaporize and freeze (yes, it does both at the same time). thus it can be used as shields to defract laser beams. of course, this isnt so effective if energy shields and phaser-blazer-megaguns exist, but its great stuff for a grit-tech mod.

since im too lazy to look up the original thread, and i wanted to ask a specific question, i have opened this new thread.

here is my delema. i am working on a grit mod, and will be using low tech stuff. i wanted to use this idea, but im having some trouble. i made all conventional weapons ship shields, so projectiles and missiles will go right through shields, if these ice fields are the only kind of shields in the game. then laser weapons would not skip shields, and would be hampered by these ice fields.

now everything should be fine, but what about boarding parties? they wont board until shields are down. do you mean to tell me that some pithy amount of ice floating through space is going to stop a few hundred kilotons of starship from latching a docking collar onto its target? i doubt it!

so how do we make this great idea work, without breaking how ship-capture works?

If its just too imposible to do, then I have also had this other idea for shields that could be modled, and would reasonably stop a boarding attempt. it is based on this technology:
