Add services to SSIS IServiceProvider model?

Is there any mechanism for being able to add custom services into the SSIS service provider model so that they can be used by components at design and runtime? i.e. if I can currently access service implementations such as the IDtsConnectionService from the Initialize method of a custom component (or in a UI type editor), is there a way to add a service of my own?

Thanks

Interesting - we've never thought about this. What kind of services do you plan to add there? Note that the services are for design time only, they are no available at runtime.|||

Thankyou for the response - actually design-time only services would still be useful in this case - I'm writing custom components against a JD Edwards Oracle database, but I'm having to interpret the data dictionary schema for business users to assist them in writing their queries (it has to be available offline).

I currently have metadata available to the components so that they can present meaningful field information to users before it is mapped onto the underlying schema, but it would be extremely useful if my components could utilise a service that wrapped this metadata functionality for them.
