It would be very nice if somebody actually spelled out the intended meaning IP for us non-English-speakers who don't use the abbreviation that often. I tried looking it up and found:
- Internet Protocol (well, a kids' area can do without a webpage).
- Instruction Pointer (I don't think processor chip machinery is required for kids to have fun. Might be wrong, though, hard to tell with today's kids).
- Immunoprecipitation (Biology stuff. No, it isn't neeeded).
- Incontinentia Pigmenti (Or Bloch-Siemens disease. It's not needed in a kids'a area, but we shouldn't discriminate kids with the disease).
- Indian Pharmacopoeia (Yep, kids areas do best without, I think).
- Infundibulopelvic ligament (It's a part of the female pelvis. I think it's somewhat needed, seeing as it's a crucial part of any girls who want to play in the area. When there's only boys there, though, it can be excluded).
- Interphalangeal joint (Parts of hands and feet. Again, a rather vital part of the kids who play there. Exception if the area is only used by amputees).
- Intraperitoneal injection (We can leave this out, unless somebody is bleeding massively).
- Imperial Police (Kids areas employing their own police departments... I enjoy the idea, but it's not needed).
- Insolvency Practitioner (Oh god, no. We have enough lawyers as it is).
- Intellectual property (Is this what you're meaning? If so, no. Shun!).
- Iraqi Police (It's understandable that Iraq wants to give something back after all those countries sent guys with guns to their country, but we should find other places for them than our kids' areas. Also, I think the world has more kids' areas than Iraq has policemen).
- Independence Party (now, THAT would be fun! Finally somebody working towards the sovereignity of Disneyland!).
- IP Code (Umm... yes, actually. Those are safety standards).
- Identified patient (I'll let Wikipedia do the talking: "a term used in a clinical setting to describe the person in a dysfunctional family who has been subconsciously selected to act out the family's inner conflicts in order to keep attention focused on an element that lies outside of the core conflict". No, I don't think it's required).
- Induced polarization (again, Wikipedia: "an electric current is induced into the subsurface through two electrodes, and voltage is monitored through two other electrodes". We don't always want to electrocute the kids, so no).
- Inflectional phrase (I'm no language expert, but I don't think it's needed).
- Integrated Programme (Let kids be kids. Academia can catch them later).
Largely inclined towards the "no" side of "maybe" here. Unless somebody can be more specific, I'll say no, it's not needed.
