[Seaside] "Boot" Page?

I suppose it depends whether you need it hooked into seaside globally or 
whether you can just do it in your application.

You obviously need to register a class with #addToStartupList:

Smalltalk addToStartupList: MyStartupClass

Then you need to implement MyStartupClass>>startUp or 

That gives you your startup hook.  Then you could put a decoration 
around the main component of your application, have it check with 
MyStartupClass to see if it has done it's startup processing, and either 
display the component or the "loading message" as appropriate. 
Obviously you could use the same decoration around as many apps as you 
want but you'd have to set each up.

Alternatively, you could certainly modify Seaside to check the class if 
you really want to go that deep.  Or, you could have MyStartupClass copy 
all the registered applications (either on shutdown or startup) and 
replace them with another application that just displays a loading page. 
  When it was done, it could put the other applications back.  This had 
the advantage of covering all your applications but feels a little 
kludgy to me.

Probably others will have other suggestions, but hopefully that gives 
you something to start with...
